SPRING-WHEEL.

ToaZZ whom itmay-conaem.' l

ai knmvnt aaLAno Mo -Ina citiz of, the United States, residi-ng at Eltopiafln the countyof Franklin and ;-State of-XVashington,;11ave inventednew and useful Improvements in Spring-Wheels, of @which the following is a specification.

,This invention relates to -I .e'sili ent wheels and has particular 7 application to a spring wheQL-the chieficharacteristic of the inven-. tion residing in the provision of a device of this chanacter comprising resilient. compressible spokes which are arranged inpairs to movably connect the telly with the hub, the spokesin each vpair being inelined inopposite directions toprevent thehubfrom-rotating-Withimthe tel-1y.

Another characteristic of this-invention resides in the provision of a deviceof this character having a cover for the resilient spokes; to; thoroughly; protectthe same under all conditionsthe cover being of novel construction to permit the expansion and contraction of the. spokes and thus not intere fering with the resiliency. of the wheel.

Another objeetofthis'; invention is to provide a. device of: this character rhavi-n-g; means for lubricating "the reciproeatingpart of the Spokes, thus: limiting; the, frictionand reducing. the. wearingof the parts. to a a minimum.

Anothen obj ect of the inventionis. to provide .a-hub of simple-and eflicient construc: tion for substantially supporting the spokes and for preventing accidental lateralimo-vee ment thereof. v

Other objectsyof the, invention will appear as the specification is read in connectionwith the e ompanying drawings, in which':

aReferring tothe drawings in detail, nay invention .comprises a ;hub generally indi-' cated as at Auiw-hich inthis instances-is provided with a pair of annular extending} flanges .1 and '2 which are-arranged in substantially parallel spaced .relation to each other and which have their outcnedgespmvi ded with alined openings-3: arranged at spaced intervals in pairs as is clearly shown Specification of Letters Batent.

It [will be ,noted that the openings being arranged in pairsti-n intervals about the periphery ,of {the flanges 1 an the; re i ien spokes 1B whi h are pivo al y mounted within. the; openings, will be arranged-impairs as is. elearly shoWnin F-ig. 3 of the drawings.

Serial No. 1945324.

The inner member 8 of each of the spokes has its j'outer' end pivotally mounted by' keep the members in retracted or extended position. Interposed' between the confronting ends of the inner and outer members 9 and carried by the outer member 9 is a sleeve bearing 8 which is adapted to engage the confronting faces of the inner and outer members so as to reduce the amount of wear between the parts to a minimum.

It will be seen from the foregoing construction that I have provided a spoke formed with telescopic sections, the sections being resiliently supported in extended position whereby upon movement of the folly toward the hub of the wheel, the springs interposed between the members or sections of the spokes will serve to prevent the hub from receiving the full impact of the jar or movement of the felly when the latter strikes any irregularity in the rod. The spokes being arranged in their converging relation to each other, the springs upon the respective pairs of spokes will cooperate with each other to minimize the amount of jar between the felly and the hub thus producing a wheel which is highly resilient and furthermore brace the hub against turning within the wheel. It will be further noted owing to the fact that the sections or members of the spokes are pivotally mounted upon the felly and hub respectively, the

. spokes may be permitted to move laterally to a certain degree to automatically position themselves to receive the full impact of the movement of the felly.

Mounted upon the felly C is a metallic tire D which has its tread surface provided with a groove 19 whereby the skidding of the tire will be prevented. Although I have shown a metallic tire secured to the wheel, I wish it to be clearly understood that a tire V of any description may be used without departing from the spirit and scope of this invention.-

Referring more particularly to Fig. 1, I have shown an improved form of cover designated as at F which is composed of two sections 22 and 23, respectively, and the spring clip 26L The section 22 is in the form of a flat annular ring which is secured to the inner flange 1 my means of the shaft 4, the other extending through the ring adjacent its inner periphery, thereby disposing the major portion 'of the ring beyond periphery of the flanges 1 and 2. The section 23 is also of annular formation and has its outer periphery secured to the felly C by means of the bolts 14, and is bent transversely so as to dispose its inner edge or periphery upon the outer side of the section 22, the inner edge being provided with an inturned annular flange 25 which is adapted to engage the section 22 to hold the section 23 in spaced relation thereto. Secured to the inner face of the'section 23 at regular spaced intervals is one end of the spring clips 24, the fixed clips being of'such a length as to have free ends engaging the inner face of the section 22. It will be noted that the clips 24 have their medial portion arranged in spaced relation to the section 23 thereby forming a slot for the reception of the section 22 and to guide the latter when the sections are moved under the vibration of the wheel. It will be noted that the space between the clips and the section 23 is of a length greater that the relative movement of the sections whereby the sections will be prevented from striking each other and consequent bending or distorting of the same when the wheel is vibrated. It is to be understood that the sections 22 and 23 are arranged upon the inner side of the wheel to prevent the dust and foreign matter from gettin into the reciprocating members of the spo es, while arranged upon the outer side of the wheel is a casing or cover 26 which is annular and of substantially cone shaped formation, the periphery of which is secured to the felly by means of the bolt 14: as is clearly shown in the drawings. The cover 26 is of such a diameter as to completely cover the outside of the wheel and has its apex disposed adjacent the axle of i the hub whereby the free movement of the axle will not be prevented and all the mecha nism within the wheel thoroughly protected at all times.

It will be evident from the foregoing that I have provided simple and efficient means for protecting the wheel from dust or other foreign matter and at the same time permitting the expansion or contraction of the spokes to accommodate the movement of the folly upon the hub.

It is thought from the foregoing taken in connection with the accompanying drawing that the construction and operatlon of my device will be apparent to those skilled in the art without further description, that minor changes in shape, size and proportion and minor details of construction may be made without departing from the spirit and scope of the appended claim.

What I claim is A resilient wheel comprising a hub section, a felly section, resilient means connecting said sections together, an annular plate connected With the hub section, an annular plate connected with the felly section and provided With an inclined portion and a straight portion having an inturned edge engaging with the outer face of the plate on the hub section, and a third plate secured to i the inner face of the inclined part and extending inwardly With its inner edge yieldingly engaging the inner face of the plate on the hub section.

In testimony whereof I aflix my signature.
